Question
Chapter 34, Problem 10TYU
Summary Introduction
To explain:
The reason that giant insects are improbable.
Introduction:
The largest insects known till now existed in the Paleozoic era. These were Paleozoic dragonflies with a wing span of half a meter. However, movies like Godzilla have shown creatures with several dozen meter wing spans. These giant insect creatures are improbable to exist.

Some patients with severe emphysema have constant high levels of carbon dioxide because of inadequate
ventilation. The central nervous system breathing center in these patients becomes insensitive to carbon dioxide and
more dependent on the level of oxygen, which is low. These patients are said to have “oxygen-dependent respiratory
drive". What might happen if you give such a person high levels of supplemental oxygen?

Birds differ from their closest relatives, the reptiles, in what ways?
(choose all that apply)
birds are capable of powered flight, while some reptiles can glide
only the birds lay eggs on land; the reptiles can only lay their eggs in water
birds have feathers, reptiles have scales
the reptiles have a series of internal air sacs that allow a very efficient extraction of oxygen
the bones of reptiles are too lightweight to permit flight
birds are endothermic, while reptiles are generally ectothermic
Swim bladders in fish and lungs in terrestrial animals have a common evolutionary origin, but have
evolved to perform different functions. What is the primary function of swim bladders in fish?
They serve as buoyancy control organs.
They filter toxins from the water.
They allow fish to absorb most of their oxygen.
They help in the digestion of food.

- Test Your Understanding 1. Which of the following is a benefit of gas exchange in air compared with gas exchange in water? (a) air has a higher concentration of molecular oxygen (b) oxygen diffuses more slowly in air (c) no energy is required for ventilation (d) moist respiratory surface is not needed (e) air is denser than waterarrow_forwardThis is my concept map below,(not a drawing) that connects the digestive, circulatory, and respiratory system. Could you recreate it exactly like that but with more pictures. Rule: don't do it like the second image do it exactly like the first image but with more picturesarrow_forwardHow do you and other large animals get enough oxygen to all of your cells to enable you to survive?arrow_forward
- What causes air to enter human lungs? The contraction of the diaphragm increases the volume of the lungs, decreasing the pressure relative to the air outside the body. Smooth muscle in the trachea guides the flow of air into the lungs. Air diffuses into the lungs due to the decreased O2 content relative to the air outside our body. The cilia in the trachea guide the flow of air into the lungs. The decreased concentration of O2 in the lungs decreases the density of that air and denser air outside the body "sinks" into the lungs.arrow_forwardAnimals breathe in air that contains more oxygen than the air they breathe out. Where is oxygen consumed?arrow_forwardBecause flight is metabolically demanding, birds have very efficient systems that help to meet these demands. Look at the following list of characteristics and choose those that contribute to the physiological demands of flight. One-way airflow respiration Endothermy Large heart Nucleated red blood cells Slow heart rate Two-cycle lung ventilation Air sacs Separate pulmonary / systemic circulation Air capillariesarrow_forward
- I am stuck on number 7 I think because mammals are more bigger so they intake more oxygen to get more energy ?arrow_forwardThere are lots of fishes that breathe air, but there are no mammals that breathe water. Why? Discuss the advantages and disadvantages of breathing either medium, and explain why air-breathing could evolve in water-breathers, but water-breathing would not re-evolve in air-breathers. Donning the hat of a "not-very-intelligent designer", design an efficient gas exchange organ of an imaginary water-breathing mammal, an endothermic homeotherm with stable core temperature of 38°C. Although evolution cannot "go back", you may tweak any of its symplesio- and synapomorphic characters as you wish, and endow it with novel autopomorphies without explaining how they have been acquired. Focus on making sure that its gas exchange organ(s) can function and sustain its metabolic rate. Apart from respiratory issues, what other problem does a mammal have to solve before it can really breathe water?arrow_forwardJay Guide The human embryo and the embryos of other animals with backbones have gill slits. According to the modern evolutionary theory, this best supports the idea: Mark only one oval. That fish are our closest relatives All embryos breathe through their gills All animals with backbones are related by common ancestry All organisms have gill slits at an early stage in their developmentarrow_forward
- 4) Animals that undergo ecdysis, or molting, include nematodes and arthropods. Why do these animals molt? Group of answer choices shedding the exoskeleton allows the animal to move faster to escape predators the exoskeleton prevents them from obtaining oxygen their outer covering is made of a non-living substance shedding the exoskeleton makes the animal smaller, which makes it easier for the animal to hide from predators in crevicesarrow_forwardSponges and cnidarians have no lungs or gills. How do they exchange gases with the environment? Are humans better off having lungs? If so, how?arrow_forwardScientists from Temple University used radioactively “tagged” carbon dioxide to determine that spotted salamander embryos Multiple Choice benefit from carbohydrates produced by the green algae living in the jelly layer of the eggs. are consuming the carbon dioxide produced by the green algae living in the jelly layer of the eggs. are producing oxygen for the green algae living in the jelly layer of the eggs. receive no benefit from having green algae living in the jelly layer of the eggs. are consuming the oxygen released by the green algae living in the jelly layer of the eggs.arrow_forward
